The LMC7660 is a CMOS voltage converter capable of converting a positive voltage in the
range of +1.5V to +10V to the corresponding negative voltage of −1.5V to −10V. The LMC7660 is a
pin-for-pin replacement for the industry-standard 7660. The converter features: operation over full
temperature and voltage range without need for an external diode, low quiescent current, and high
power efficiency.
The LMC7660 uses its built-in oscillator to switch 4 power MOS switches and charge two
inexpensive electrolytic capacitors.
